Cardio IQ Vitamin D, 25-Hydroxy
Cardio IQ® Vitamin D, 25-Hydroxy - This test measures the levels of Vitamin D in your body, which is crucial for bone health. It's especially useful for people without kidney disease. Low levels of Vitamin D can lead to bone issues like rickets in children and osteomalacia in adults, while high levels can cause hypercalcemia. This test specifically looks at two forms of Vitamin D: 25OH D₃ (the type your body makes) and 25OH D₂ (a form used to treat Vitamin D deficiency).

Stephanie Strudley, CNS, is a functional medicine nutritionist and the founder of Upstream Wellness. She helps driven, health-conscious adults who've done "everything right" and still don't feel like themselves — connecting the dots between symptoms, labs, and lifestyle to uncover what's actually going on. Her approach is shaped by an unconventional path: a background in ecology and systems biology, and her own experience navigating serious, unresolved health challenges before finding root-cause care herself. She doesn't believe in one-size-fits-all protocols or quick fixes — she believes health is more like solving a puzzle than following a formula, and her role is to help clients ask better questions, interpret their own data, and build a plan that fits their unique biology and life.
